Would you draw them, please? As for your pose and facial practice, they could be training with each other, the girl with a determined face, the boy trying his best to not fall easily? Just a suggestion ♥
She's not really a totally fleshed-out OC, but I did put a bit of thought into the kind of person she could be while I was painting her. She is petite, elegant, gentle and god-like. She is the caretaker of the deep sea. She is able to manipulate creatures into peaceful submission, an ability which protects her from the rouge creatures of the deep- Though most animals generally let her be. She is graceful and whimsical. She see's beauty in even the most grotesque creatures. She cannot speak.
